Parsec-scale SiO Emission in the Galactic Center

The Astrophysical Journal
The central 5 pc of our Galactic center is rich in various molecular tracers. The region is observed to be hot, highly ionized, and volatile, resulting in complex chemistry and kinematics.

Subclustering and Star Formation Efficiency in Three Protoclusters in the Central Molecular Zone

The Astrophysical Journal Letters
We present the highest-resolution (∼0 $\mathop{.}\limits^{^{\prime\prime} }$ 04) Atacama Large Millimeter/submillimeter Array 1.3 mm continuum observations so far of three massive star-forming clumps in the Central Molecular Zone (CMZ), namely 20 km s ...

Detection and Evolution of Linear Polarization of the Galactic Center Transient MAXI J1744-294

The Astrophysical Journal
MAXI J1744−294 (MAXI J1477), likely a low-mass X-ray binary system, is a Galactic center transient source, detected at radio and X-ray wavelengths, located approximately 19″ southeast of Sgr A*.

First Mid-infrared Detection and Modeling of a Flare from Sgr A*

The Astrophysical Journal Letters
The time-variable emission from the accretion flow of Sgr A*, the supermassive black hole at the Galactic center, has long been examined in the radio-to-millimeter, near-infrared (NIR), and X-ray regimes of the electromagnetic spectrum.

Magnetic Field Strengths in the Vicinity of Sgr A* via 18 cm Zeeman Observations

The Astrophysical Journal
Very Large Array (VLA) observations of 18 cm OH absorption lines were used to determine the strength of the line-of-sight magnetic field in the Galactic center region. This study is an extension of the VLA OH Zeeman observations of Killeen et al.

Modeling the Radial Distribution of Pulsars in the Galaxy

The Astrophysical Journal Letters
The Parkes 20 cm multibeam pulsar surveys have discovered nearly half of the known pulsars and revealed many distant pulsars with high dispersion measures.
